Design of Remote Control System for Automatic Ship Operation : Design of Remote Experiment System Using E-mail

Abstract

The authors propose a remote control system which uses the communication line to achieve an automatic operation of the ship. It is necessary to integrate the inormation which affects the ship operation. Recently, the computer system inboard, caled inboard LAN, is established to integrate the information generated inboard. However, the means to treat information integrated has not been established in the communication between land and the ship. Although the e-mail system which is one of communication methods in Internet can treat only the text data, the data of the voice, the image, and animation, etc. can be treated integrated by using the MIME expansion. It is useful for making of the communication between land and the ship to be integrated. However, because only the communication in a single direction is defined in the e-mail system, it will be impossible to use it for remote control of the ship without any improvement. Thus, the design of the remote control system which uses e-mail is examined in this paper. We take remote use of research data processing system installed in Shiojimaru of The Tokyo University of Mercantile Marine as an example of the remote control system of the ship. In this thesis, first of all, the outline of research data processing system of Shiojimaru is introduced. Next, the flow of information by the experiment onboard in the past is brought together and a necessary function for the experiment system is examined. We design the remote experiment system of Shiojimaru which used e-mail based on them.
